Ldap_mutexfunctions for implementing mutexes on top of LDAP's built in test and set mechanism. In order to use this module you must load mutex.schema, which is an rfc2252 format schema file. raised when a mutex operation fails. The string argument contains the name of the method which failed, and the exception contains details about what failed.

val apply_with_mutex : mutex -> (unit -> 'a) -> 'aused to apply some function, first locking the mutex, unlocking it only after the function has been applied. If the function generates any exception, this wrapper catches that exception, and unlocks the mutex before reraising the exception. Generally garentees that the mutex will always be used consistantly when performing an action.
